There are two distinct methods to eliminate the leakage current in the solar PV array system: (i) obstruct the leakage current, (ii) reduce the variation/constant common-mode voltage. The additional diodes/switches are incorporated in the system to obstruct the leakage current by disconnecting the PV array from the grid side network.
Due to the removal of transformers, the leakage current appears in the system because of changes in common-mode voltage (CMV) across the parasitic capacitance, which appears between the PV module and the ground .
Therefore, the leakage current is attained within permissible limits as per the revised VDE-00126-01 standard as evinced in Fig. 6a. Fig. 6b and Figs. 7a and b show the response of SECS at the variation of solar irradiation from 1000 to 800 W/m 2.
Because of the superstrate technology no barrier layer is between the glass and the TCO layer. That leads to an extreme boost of the leakage current of this module. The maximum value reaches 340 μA. In comparison to the unbroken modules the maximum value reaches 12 μA. This is similar to the negative potentials.
Multiple requests from the same IP address are counted as one view. This paper proposes an optimized predictive control strategy to mitigate the potential leakage current of grid-tied photovoltaic (PV) systems to improve the lifespans of PV modules.
The additional diodes/switches are incorporated in the system to obstruct the leakage current by disconnecting the PV array from the grid side network. The second approach involves the elimination of zero switching states . To address the aforementioned issues, the transformerless SECS is presented in .
